How to Demonstrate the Energy Of Candy (Gummi Bears Vs. M&M's)

Hyperactive kids, could this be the cause? This demonstration will open your eyes to the amount of energy stored in these little candies.

What you do is melt a small quantity of potassium chlorate in a large test tube clamped to a ring stand. Use long-handled tongs to introduce a Gummi Bear candy to the test tube. The sugar in the candy reacts vigorously with the potassium chlorate, causing the bear to 'dance' amidst bright purple flames.

Lets consider the mis-information in the video, it trys to show the "energy" stored in the candy, yet that energy is released due to the KClO3 along with the candy. This isn't energy that you absorb when digesting candy. No offense whatsoever to the creator was mean by the above comment, it was a really fun video to watch .

Question... How much of the released energy is from the candy and how much is from the potassium chlorate? I liked the video, but I think that it may be a little misleading unless the energy was released only from the Candy.
